PINELLAS PARK, Fla.- Detectives have arrested a teacher at Cross Bayou Elementary. He's charged with possession of child porn after investigators say they found at least seven videos and hundreds of images depicting the sexual penetration of children between the ages of 8 and 12 years old.

Investigators say 42-year-old John Kaneski of Dunedin is an ESOL (English Speakers of Foreign Languages) teacher at the school. Many of his students are around the same age as those found on his computer's hard drive.

Pinellas County Sheriff Bob Gaultieri held a news conference shortly after the arrest. "We're not going to tolerate it. This is absolutely egregious, this is gross conduct," he said Sheriff.

On top of the downloading and dissemination of images, the sheriff says detectives are also investigating new allegations that Kaneski may have sexually abused at least one child. The sheriff would not say if the child was a student at the school.

This is not the teacher's first time under investigation on sex abuse charges. In 2005, the sheriff says an 8-year-old student from Curlew Creek Elementary School in Palm Harbor accused Kaneski of sexually abusing her. Investigators say in that case the girl eventually changed her story, and as a result the case was closed.

"It's troubling," Sheriff Gaultieri said of the new allegations.

Kaneski lives in a waterfront home on Edythe Drive in Dunedin. Neighbors say they saw deputy cruisers at the home Friday morning, but had no idea what was going on.

"I'm still numb from you telling me that this was happening two doors down. I don't even have a reaction to that," said neighbor Don Hess.

"It's not only hard to understand it's just ... incomprehensible, especially, a person who is in that position."
